Here is what the readouts mean:
1. In car temperature, from the sensor near the dome light: 80 degrees F.
2. Outside temperature sensor: 90 -103 degrees. Not sure where this senor is located.
3. Left heater core temperature: 46 degrees.
4. Right heater core temperature: 46 degrees.
5. Evaporator temperature sensor: 46 degrees.
6. Engine coolant temp: 182 degrees.
7. Refrigerant pressure: 14 bars (~198PSI)
8. Refrigerant temperature: 136 degrees.
9. Not used.
10. Blower control voltage: 4.3v (range is 0-6)
The numbers don't look too bad, and nothing abnormal. Ultimately you want to evaporator temp to drop another 10 degrees, but whether or not you have a problem depends on how long the car had been running, how hot & humid the weather was, etc.
If it's still not cooling well, I think you need someone with a real set of guages to check the high & low side pressures. As well look for a restriction in the high side line. You can find restrictions by checking the temperature of the high side line (see item 8 above) while the a/c is running. It will be hot until the restriction, after which it becomes cold.
